The dance committee of Pine Bluff Middle School earns \$72$72dollar sign, 72 from a bake sale and will earn \$4$4dollar sign, 4
Brut [27]

Answer:

The correct answer is 72 + 4 × x \geq 400.

Step-by-step explanation:

The dance committee of Pine Bluff Middle School earns $72 from a bake sale and will earn $4 for each ticket they sell to the Spring Fling dance.

The dance will cost $400.

Let x number of tickets the committee could sell.

Total money earned is 72 + 4 × x.

The committee should have some left over money also after spending for the dance which costs $400.

Thus the inequality to determine the number of tickets the committee could sell to have money left over after they pay for this year's dance is given by,

72 + 4 × x \geq 400.

To find the median, find the middle number. Since there are 10 numbers, find the 5th one and the 6th one and find their average.

The two numbers are both 9, so its safe to say that the median is 9.

to find the median of the first and quartile, you have to place a line where the median should be and find the median of that. Q1 and Q2 will be 5 and 11 (respectively).

Its easy to see that all the lines start at the lowest point given and end at the largest point given, so match Q1, the median, and Q3

The only line that has lines at the Q1, median, and Q3 we figured out is answer C, so therefore it is the answer.

8x+11=14-1x how does it work
Alenkinab [10]

Answer:

x = 1/3

Step-by-step explanation:

Step 1: Write equation

8x + 11 = 14 - 1x

Step 2: Solve for <em>x</em>

  1. Simplify: 8x + 11 = 14 - x
  2. Add x to both sides: 9x + 11 = 14
  3. Subtract 11 on both sides: 9x = 3
  4. Divide both sides by 9: x = 3/9
  5. Simplify: x = 1/3

Step 3: Check

<em>Plug in x to verify it's a solution.</em>

8(1/3) + 11 = 14 - 1(1/3)

8/3 + 11 = 14 - 1/3

41/3 = 41/3

A house worth $70,000 when purchased was worth $67,000 after the first year and $64,000 after the second year. If the economy do
Citrus2011 [14]

Answer:

a) The formula for the sequence is

a_n = 67,000 -3,000(n-1)

b) a_7 = 49,000

Step-by-step explanation:

Note that the difference between any two consecutive terms in the sequence is always equal to $3,000

67,000-70,000= -3,000\\\\64,000-67,000=-3,000

Then we have an arithmetic sequence where each term increases by a magnitude of 3,000 with respect to the previous term.

The explicit formula for an arithmetic sequence is:

a_n = a_1 +d(n-1)

Where d is the common difference between the consecutive terms of the sequence

d = -3,000

a_1 is the first term, or the value of the house after year 1 a_1= 67,000

n represents the number of years since the house was purchased

With

n={0, 1, 2, 3, 4, 5, 6, 7,.., n}

a) Then the formula for the sequence is

a_n = 67,000 -3,000(n-1)

With

n={0, 1, 2, 3, 4, 5, 6, 7,.., n}

---------------------------------------------------------------------------------------------

b) Now we can use the formula to find the price of the house after 7 years

a_7 = 67,000 -3,000(7-1)

a_7 = 67,000 -3,000(6)

a_7 = 49,000
